If you really, really need chromecast protocol, get an android TV instead of a roku or a separate chromecast device. If you are playing from files, you can use a server like Plex on your computer to send them, or put them on a USB drive to play with the roku media player, or put them on a phone or tablet and send them with the roku app. Even if you have your own content, you can simply use a media server.

If you are playing content from the internet, chances are there is a roku app to play it directly. Screen mirroring is generally not the best way to consume media on a Roku, since its built-in apps are much more intuitive.

Generally, screen mirroring of some other device is inefficient and not the best way to view things even where it does work. YouTube/Netflix/Plex and possibly others may work this way on the roku (you'll know because the phone app itself will show the cast icon). Some applications provide their own 'casting' function where the phone app tells the TV app what content to play but the TV app gets its own copy. Chromecast works over your existing network connection but the screen mirroring part does not work on the roku. The screen mirroring that roku provides is 'miracast' which requires a wifi-direct connection between the devices, and not all PC hardware can do that.
